The isotopic difference in the thermodynamics of hydration of 20 mol% Y-substituted BaZrO 3 with H 2 O or D 2 O has been investigated by thermogravimetry. Average standard entropies and enthalpies of hydration were extracted from linear regressions of van ‘t Hoff plots of hydration over the range 400–900 °C, further v…
Polylactic acid (PLA) is one of the most promising bio-based and biodegradable polymers, yet its inherent brittleness limits its application in flexible film products. This study compares three mixing strategies, applied as four sample series, to improve the mechanical performance of PLA-based binary blends: (1) singl…
ABSTRACT Thermal depolymerization is typically studied in bulk, yet many systems involve polymers confined within nanoscale geometries. Understanding how nanoconfinement alters radical depolymerization kinetics is essential for interpreting polymer stability in nanostructured environments. Here we show that thermal de…
Abstract Nanoscale quantum light sources are essential building blocks for integrated quantum photonic systems. Here, we report a wavelength-scale entangled-photon source based on van der Waals-engineered NbOBr2 and benchmark its performance for telecom-wavelength quantum light generation. By exploiting the material’s…
Ballistic impact involves the high-velocity interaction response of a projectile with a protective target, resulting in projectile deformation, target damage, and mass loss. The Finite Element Method (FEM) implemented in ANSYS/Autodyn was used to investigate the ballistic response of a Kevlar Fiber Reinforced Polymer…
The need to optimize photoluminescence (PL) signal-to-background ratios for demanding applications in bioanalysis and imaging has led to an ever-growing toolbox of light-emitting materials with diverse strengths and weaknesses. Although the long PL lifetimes of luminescent lanthanide complexes (LLCs) support time-gate…
The effects of ultrasonic amplitude (A; 50–80%), sonication time (T; 5–10 min), and pumpkin seed oil (PSO) concentration (C; 10–30%) on the physicochemical and rheological properties of gelatin–acetic acid polymer solutions and their corresponding PSO emulsions prior to electrospinning as well as on properties includi…
Abstract Electrode plate contact abnormalities are one of the key factors affecting current efficiency in the zinc electrolysis process. Recent studies on infrared image-based detection of electrode plate contact abnormalities have demonstrated promising performance under conventional scenarios. However, in real indus…
Abstract Multiple stimuli-responsive crystalline materials have attracted huge attention in versatile fields. Solvent strategy for regulating structures and properties is effective but remains underexplored. This work achieved the integration of multiple stimuli responses including photomechanical, thermomechanical, f…
ABSTRACT The plant‐mediated biosynthesis of metal oxide nanoparticles (MONPs) has gained significant attention as a green, cost‐effective, and sustainable alternative to conventional chemical and physical synthesis methods. By utilizing bioactive phytochemicals such as phenolics, flavonoids, alkaloids, terpenoids, and…
Abstract Achieving fail-safe normally-off operation without plasma-induced damage remains a significant challenge in β-Ga2O3-based high-power electronics. We demonstrate a forward metal-assisted chemical (f-MAC) etching that functions as a damage-free and self-aligned process for recessed-gate β-Ga2O3 metal–semiconduc…
ABSTRACT Silicone rubber (SR) is limited by its inherent flammability and heavy smoke generation. Inspired by natural hierarchical structures (e.g., nacre, bone) where organic–inorganic synergies create exceptional properties, this study developed a bio‐inspired organic–inorganic hybrid flame retardant, gum arabic‐mod…
FINDING: Discovery of quasicrystals with forbidden five-fold rotational symmetry, enabled by Penrose tiling and the golden ratio, disproving the classical crystallographic restriction theorem. MATH: - Crystallographic restriction theorem: periodic lattices in 2D/3D allow only 1-, 2-, 3-, 4-, 6-fold rotational symmetri…
FINDING: Sumerian/Babylonian base-60 mathematics encodes reciprocal pairs and proportional fractions (igi-n-gál, igi-te-en) with potential geometric significance for transport corridors. | MATH: Base-60 (sexagesimal) system; reciprocal pairs: igi-n-gál = 1/n (e.g., igi-2 = 30, igi-3 = 20, igi-4 = 15, igi-5 = 12, igi-6…
Extracting governing mathematical laws directly from raw empirical datasets is a fundamental challenge in scientific computing and artificial intelligence. Classical symbolic regression methods suffer from combinatorial search spaces, while pure deep learning approaches lack mathematical interpretability. In this pape…
Magnesium alloys are the lightest structural metallic materials (density ρ = 1.3–1.65 g cm⁻³) and possess a range of attractive properties, including good castability, excellent damping capacity, superior electromagnetic shielding performance, favourable biocompatibility, and environmental sustainability. These attrib…
Abstract This study investigates the enhancement of the antimicrobial activity of α-Ag2–2xMxWO4 microcrystals, where Mx represents Cu1.15 and Zn1.16, through femtosecond (fs) and nanosecond (ns) laser irradiation. The research highlights how laser exposure induces significant changes in the structural properties of th…
The influence of chemical water treatment (CWT) sludge in standard elastomer compositions based on polyisoprene rubber SKI-3 and methylstyrene rubber SKMS-30 ARKM-15 was studied. The effect of CWT sludge additives on the rheological and physico-mechanical properties of vulcanizates was investigated in comparison with…
